For over 25 years we have been supplying pumps to commercial aquarium applications. Our pumps can be found in Shark Reef at Mandalay Bay, Sea World in San Diego and in the new Atlanta Aquarium. ReeFlo was started in 2000 by Sequence Pumps to bring the benefits of commercial duty pumps to the aquarium consumer. Commercial duty means energy efficiency, quiet operation and maximum durability. There are so few problems with our pumps that, ReeFlo will replace your pump if you encounter a warrantied problem! We uses Baldor, A.O. Smith and Marathon electrical motors all are Totally Enclosed Fan Cooled (TEFC) Motors. These motors are more expensive than the magnetic drive and open vented motors used by our competitors. TEFC motors ensure efficient and cool operation. We back up our pumps with a 3 year replacement warranty direct from ReeFlo to you.
